What Is Technical SEO?
Technical SEO is a term that is used to describe the process of making your website more organized to allow search engines to crawl, index, and comprehend your content in a more efficient manner. Compared to content-based techniques, technical SEO addresses a group of measures, such as site speed, mobile responsiveness, XML sitemaps, structured data, and HTTPS security.
It makes sure that your website is well structured, optimized, and accessible to the users and search engine robots. With good technical SEO, the search engines can find your pages with ease and learn the context as well as rank them accordingly on the search results, hence finally attracting more organic traffic to your site.
